+# Detected next.config.js, no exported configuration found
+
+#### Why This Warning Occurred
+
+There is no object exported from next.config.js or the object is empty.
+
+#### Possible Ways to Fix It
+
+Check if you correctly export configuration in `next.config.js` file:
+
+```
+module.exports = {
+  /* config options here */
+}
+```
